I know raw is not for everyone, can cost the same as kibble sometimes.
I just looked up the other formulas from the brand you said(haven’t looked at ocean recipe yet), but they all use lots of peas, and lentils which is a huge contributor to DCM.
A lot is still unknown about DCM.
But based on the ingredients and additives used in the food, it’s low quality protein being used, I know that because there are added synthetic vitamins being used which don’t actually need to be added(and also aren’t absorbed by the dog eating it and it causes more harm than good). When high quality protein and other high quality ingredients are used, there is no need to add synthetic vitamins in because the high quality protein is used which is where they get the vitamins from.
You can get good kibble, without having the risk of DCM and that also don’t have synthetic vitamins added.
Frenchies don’t usually tolerate grains and it often causes other Heath issues and inflammation-especially in Frenchies!
I know it’s very frustrating and confusing when the breeder says one thing and the vet says a different thing(I have been thru the same thing before I did my courses in dog nutrition), it’s very confusing and frustrating. It depends on the formula and even grain included foods have been recalled due to DCM. The Royal canin and hills and purina ( all 3 of these foods is what vets recommend and they al have been recalled for DCM and it’s all the garbage and fillers causing the issue, using cheap ingredients for protein and less meat).
Vets have no nutrition training, same with doctors, you don’t ask your doctor nutrition advice, you have to do the same with dogs, do your research(which vets also need to do), or ask someone who knows dog nutrition.
I work at a holistic wellness pet store and get asked this every day as well as allergy and skin issues(also lots of Frenchies come in).
I know a few kibble brands that have worked good for grain issues, no synthetics and also no risk of DCM.
If your interested I can give you detail on those kibbles?
I’m happy to help
